4-Formylphenylboronic acid is a substrate for Suzuki cross-coupling reactions and it can be used as a reagent for:- Palladium-catalyzed Suzuki-Miyaura cross-coupling in water.
- Copper-mediated ligandless aerobic fluoroalkylation of arylboronic acids with fluoroalkyl iodides.
- Ligand-free copper-catalyzed coupling of nitro arenes with arylboronic acids.
- Triethylamine-catalyzed three-component Hantzsch condensations.
- Copper-catalyzed nitrations.
- Oxidative mono-cleavage of dialkenes catalyzed by Trametes hirsuta.
- Palladacycle-catalyzed cross-coupling of arylboronic acids with carboxylic anhydrides or acyl chlorides.
- Palladium-catalyzed aerobic oxidative cross-coupling reactions.
- The synthesis of sensitizers with dithiafulvenyl unit as electron donor for high-efficiency dye-sensitized solar cells.
- The synthesis of a novel protein synthesis inhibitor active against Gram-positive bacteria.
- The Suzuki aryl-aryl coupling of the upper rim of hexahomotrioxacalix[3]arene.
- A rhodium-catalyzed cyclization, converting 1,5-enynes to cyclopentenes and spiro-cyclopentenes.
Synthesis
Potassium phenyltrifluoroborate (184 mg, 1.00 mmol) was added to a solution of iron trichloride (185 mg, 1.10 mmol) in 3 mL of 1:1 THF/water. The mixture was stirred at room temperature for 30 min. The reaction mixture was then passed through a short column containing neutral absorption alumina. The alumina was then washed with a mixture of ethyl acetate/hexanes (2:1) to obtain 4-Formylphenylboronic acid (105 mg, 86%). [The boronic acid products can also be isolated by simple extraction techniques.]4-???????? ?? ?? ? ???
